I don't know what rhetorical devices these themes fall under. I know all these are themes but the themes are harder to figure out .

1. The value of dreams can be both a positive and be both a positive and negative influence.
2. It is important for men and women to play supportive roles in family structures.
3. Both men and women can and should weld power- political, economic, social, and psychological.
4. The importance of family is strong enough to overcome the temptation to give up dreams.
5. Values, ideals, and morals are worth fighting for.

These are all themes in "A Raisin in the Sun." I don't understand your question. You do not understand the five themes? Or do you need examples from the play? What is the confusion?
